Finalists for 2014 Green Car of the Year announced

The list of finalists for the 2014 Green Car of the Year has been announced, and in a genuinely bizarre twist, there's only one hybrid and no electric vehicles among the five contestants, despite the arrival of cars like the BMW i3 and Tesla Model S. Taking the place of the EVs are a pair of diesels, repping a technology that last won a Green Car of the Year award in 2009, when the Audi A3 TDI took the title. No diesel was in the running for last year's award.
Naturally, both of the diesel finalists are fielded by the Germans - with BMW's 328d and Audi's A6 TDI getting the nod. In the case of the 3 Series, BMW installed a 2.0-liter, turbodiesel, capable of delivering 180 horsepower and 280 pound-feet of torque, while returning 45 miles per gallon on the highway. Audi and its larger, 3.0-liter, V6 turbodiesel produce quite a bit more grunt, with 240 hp and 428 lb-ft of grunt, but net a very impressive 38 mpg on the highway in the A6.
Finalists for this year's awards include two diesels, three gas-powered cars and a plug-in hybrid.

2015 Audi Q3

There are two ways to approach a brand-new segment in the auto industry. First, an automaker can take a gamble and introduce a completely new vehicle, catering to the specific demands of the marketplace(s) in question. In the compact, premium CUV segment, we've seen Buick do this with the Encore, and Mercedes-Benz with the GLA-Class. The other option is to introduce a vehicle already sold in another market. Considering the amount of time it takes to bring a new vehicle from paper to production, there is plenty to gain in the short-term with this approach. It's not without its downsides, though, as we found after a week behind the wheel of the 2015 Audi Q3, a vehicle that was initially launched in 2011. Cute though it may be – it was referred to at least once by a passerby during our testing as "totes adorbs" – Ingolstadt's decision to introduce a vehicle that's already been on sale for four years, and is effectively approaching the last half of its lifecycle, leaves the Q3 at a significant disadvantage relative to the newer competition. Despite crossing its first auto show stage four years ago, the Q3 remains a handsome little bugger. Audi's designs, while conservative, tend to age very well, and the compact Q3 is no exception. It's like a scaled-down Q5 in most respects, although certain design pieces, like its more aggressively raked rear window and shorter front and rear overhangs, belie the significantly smaller Q3's figure. Due to its age, the Q3 was, fortunately, designed before the current A3 hit the market. That means it avoids the unattractive, minimalist dash of the A3, opting for a more traditional Audi design, with a strip of brushed aluminum on the passenger's side, a user-friendly center stack and a suitably large nav screen front and center. While the overall layout is attractive, the material quality is not what we'd expect of a newer Audi. There's nothing that feels exceedingly cheap – the plastics just feel old and too familiar. It's difficult to describe, but as soon as you climb in the Q3, things like the switchgear for the HVAC controls immediately remind you that this is a vehicle that's been on sale since 2011. While our definition of interior quality has evolved over the years, our idea of a driver-friendly cabin has not. The Q3 scores highly in this regard, featuring the elevated seating position that makes CUVs so popular with the general public.

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.
